House Extensions for Lymm homeowners
Blades Building — a Warrington-based Ltd company covering Lymm and the wider Cheshire area. Rated 10/10 on Checkatrade across 36 reviews.
Well-known Cheshire canal village with conservation areas and sandstone cottages. That mix matters when you're planning house extensions — a project on the kind of property near Lymm Dam and the Bridgewater Canal (think period cottages, sandstone villas and prime detached homes) isn't the same job as one on a newer estate off M6 J20 / M56 J9, and the price and the sequence should reflect that.

What we typically specify for Lymm jobs
Lymm house extensions — questions we're asked
Can you match the brickwork on older Lymm homes?
Yes. On period stock around Lymm Dam and the Bridgewater Canal we source reclaimed facings and colour-match mortar so the new wall reads as part of the original elevation, not an obvious add-on.
Do I need a Party Wall agreement in Lymm?
If the extension sits on or within 3m of a shared boundary — common on the semis and terraces around Oughtrington and Statham — a Party Wall notice is required. We can point you at surveyors we've worked with.
Will access be a problem on a tight Lymm plot?
Plenty of Lymm homes have side-return access under 900mm. We plan skip position, muck-away and materials drops around M6 J20 / M56 J9 and neighbours so the street stays workable.
Do I need planning permission for an extension in Lymm?
Many single-storey rear extensions in Lymm (WA13) fall under Permitted Development, but Warrington Borough Council treats conservation areas, Article 4 zones and larger two-storey work differently. We'll tell you honestly on the first visit which route your project needs.
Do you handle the structural steelwork yourself?
Yes — we install RSJs and pad-stones in-house so the shell doesn't wait on a separate steel contractor showing up.
